# For a support bot, should I fine-tune OpenAI or keep improving the prompt?

I’m building a small customer-support bot and want its replies to sound consistent: calm, concise, and not overly formal. We have a few hundred approved examples, but the prompt is already getting long as we add more rules.

At what point is fine-tuning worth testing instead of continuing to refine the prompt and examples? I’m especially interested in how people judge whether the change actually improves **consistent house style** without making the bot less reliable on unusual questions.
